Patent number: 8045530Abstract: A method and device for routing data packets of a wireless terminal device in a communication network. When Open system Authentication is used, the system operates similarly as the current Nokia Operator Wireless LAN system, in which the terminal device and the access controller are the parties involved in the authentication. The access controller relays information relating to the authentication between the terminal device and an authenticating server, and it is capable of updating independently the list of users it maintains. When authentication according IEEE 802.1X authentication, the access point operates according to the IEEE 802.1X standard, serving as the authenticating party and relaying information relating to the authentication between the terminal device and the authentication server. In addition, the list maintained by the access controller is updated after a successful authentication, for example by the access point or the authenticating server.Type: GrantFiled: January 21, 2003Date of Patent: October 25, 2011Assignee: Nokia CorporationInventors: Henry Haverinen, Anton Bush, Jyri Rinnemaa, Mike P. Smith, Timo Takamäki, Jukka Tuomi, Hannu Tuominen

Patent number: 8036637Abstract: A method for billing in a packet data network (WISP1) comprising at least one user's terminal (MN), comprising the steps of: forming a data link between the terminal and the packet data network; requesting a user identity from the terminal; generating billing data based on the user identity; and sending the billing data to an accounting server (HAAA) of an external telecommunications network.Type: GrantFiled: June 17, 2008Date of Patent: October 11, 2011Assignee: Nokia CorporationInventors: Juha Ala-Laurila, Jyri Rinnemaa, Jukka-Pekka Honkanen, Timo Takamaki, Raimo Vuonnala, Jan-Erik Ekberg

Patent number: 7512796Abstract: Authentication method for authenticating a mobile node to a packet data network, in which a shared secret for both the mobile node and the packet data network is arranged by using a shared secret of the mobile node and a telecommunications network authentication centre. In the method, the mobile node sends its subscriber identity to the packet data network together with a replay attack protector. The packet data network obtains authentication triplets, forms a session key using them, and sends back to the mobile node challenges and a cryptographic authenticator made by using the session key. The mobile node can then form the rest of the authentication triplets using the challenges and then form the session key. With the session key, the mobile node can check the validity of the cryptographic authenticator. If the authenticator is correct, the mobile node sends a cryptographic response formed using the session key to the packet data network for authenticating itself to the packet data network.Type: GrantFiled: July 25, 2006Date of Patent: March 31, 2009Assignee: Nokia CorporationInventors: Henry Haverinen, Jukka-Pekka Honkanen, Antti Kuikka, Nadarajah Asokan, Patrik Flykt, Juha Ala-Laurila, Jyri Rinnemaa, Timo Takamäki, Raimo Vuonnala, Jan-Erik Ekberg, Tommi Mikkonen, Petri Aalto, Seppo Honkanen

Patent number: 7480933Abstract: A method and device for ensuring address information of a wireless terminal device in a wireless local area network, the network comprising; an access point for setting up a communication connection to the terminal device, the method comprising establishing a communication connection between the terminal device and the access point (101), and relaying data packets from the terminal device to the network and from the network to the terminal device (105). The method further comprising the steps at the access point: detecting an IP address of the terminal device in response to the established communication connection (103), associating the detected IP address of the terminal device to the MAC address of the terminal device (104), and comparing that the address information of the terminal device on the relayed data packets are corresponding to the associated address information (111, 112).Type: GrantFiled: May 1, 2003Date of Patent: January 20, 2009Assignee: Nokia CorporationInventors: Anton Bush, Henry Haverinen, Jyri Rinnemaa, Mike Smith, Timo Takamäki, Jukka Tuomi, Hannu Tuominen

Patent number: 6781954Abstract: Methods and apparatus for signal monitoring of messages in a telecommunications network having a plurality of switches and network elements therein alleviate the need for external hardware to be hooked up to nodes of the network to determine whether faults have occurred at the nodes. A signal monitoring application disclosed herein stores related message signals and messages in a relational database wherein messages and signals having common elements can be easily and quickly viewed. The SIMO application cross-references the messages and signals in the relational database according to a transaction table which categorizes and stores the messages according to parameters set out in the transaction table. This allows the messages to be ranked and viewed very quickly without the need to process them and expend valuable computational time and resources.Type: GrantFiled: January 12, 2000Date of Patent: August 24, 2004Assignee: Nokia Networks OyInventors: Petri Aalto, Timo Takamäki
